This one might be for Eric!
I am running data from Touchdesigner into Pangolin Beyond via the Pangolin Chop.
The patch does this:
Plays back 2 x FBX files with mocap data.
This drives some simple models made from merged primitives.
This data goes Sop to Chop, gets resampled , filtered, then back into a Limit SOP.
So you get a curvy animated line drawing with exactly 300 points per frame.
There are also some extras like colour and switching models.
It’s a 15 min timeline with each FBX controlling a single character.
FBX Playback happens using indexed frames and Timeline Chop.
So seemed to be all working fine, but Pangolin crashes every 10 mins or so.
Not a hard crash, but GUI becomes unresponsive.
Sometimes it keeps outputting for a bit.
Sometimes the output stops.
But you can’t use any of the GUI at all. Or (worringly) disable the laser output.
Only thing to do is to End Task in Task Manager and restart.
It seems to happen only on the edit points in the FBX files, where we cut from one take to another.
I’ve noticed that the data in the Pangolin CHOP node at this point goes from the 6 channel ‘Black BG with coloured lines look’ to the ‘Timesliced Grey BG with 6 channels’ look.
Convinced this has something to do with it. But can’t think what I’m doing wrong here.
My assistant compiled the mocap takes in Houdini.
Can;t think why editing between takes would cause a crash.
There doesn’t appear to be any change in point numbers when I monitor things.
And of course, because it only crashes every 10 mins or so, it;'s a bugger to track down.
It’s also not consistent. I can’t make it crash by going to a certain frame range.
It does not crash if I get it to loop a section where there are no cuts in the FBX data.
The obvious route is to re-export the FBX’s but I’ve done that 3 times now, with various different arrangements and have not hit the magic formula yet.
Any advice gratefully received. GOing to limp through a dress rehearsal tomorrow but would love to get this stabilised!
